Install (iOS 10+)


Add the following to your

and follow these instructions
github "optonaut/ActiveLabel.swift"


CocoaPods 0.36 adds supports for Swift and embedded frameworks. To integrate ActiveLabel into your project add the following to your

platform :ios, '10.0'

pod 'ActiveLabel'


import ActiveLabel

let label = ActiveLabel() label.numberOfLines = 0 label.enabledTypes = [.mention, .hashtag, .url] label.text = "This is a post with #hashtags and a @userhandle." label.textColor = .black label.handleHashtagTap { hashtag in print("Success. You just tapped the (hashtag) hashtag") }

Custom types

let customType = ActiveType.custom(pattern: "\\swith\\b") //Regex that looks for "with"
label.enabledTypes = [.mention, .hashtag, .url, customType]
label.text = "This is a post with #hashtags and a @userhandle."
label.customColor[customType] = UIColor.purple
label.customSelectedColor[customType] =

label.handleCustomTap(for: customType) { element in print("Custom type tapped: (element)") }

Enable/disable highlighting

By default, an ActiveLabel instance has the following configuration

label.enabledTypes = [.mention, .hashtag, .url]

But feel free to enable/disable to fit your requirements

Batched customization

When using ActiveLabel, it is recommended to use the

method to customize it. The reason is that ActiveLabel is reacting to each property that you set. So if you set 3 properties, the textContainer is refreshed 3 times.

When using

, you can group all the customizations on the label, that way ActiveLabel is only going to refresh the textContainer once.


label.customize { label in
    label.text = "This is a post with #multiple #hashtags and a @userhandle."
    label.textColor = UIColor(red: 102.0/255, green: 117.0/255, blue: 127.0/255, alpha: 1)
    label.hashtagColor = UIColor(red: 85.0/255, green: 172.0/255, blue: 238.0/255, alpha: 1)
    label.mentionColor = UIColor(red: 238.0/255, green: 85.0/255, blue: 96.0/255, alpha: 1)
    label.URLColor = UIColor(red: 85.0/255, green: 238.0/255, blue: 151.0/255, alpha: 1)
    label.handleMentionTap { self.alert("Mention", message: $0) }
    label.handleHashtagTap { self.alert("Hashtag", message: $0) }
    label.handleURLTap { self.alert("URL", message: $0.absoluteString) }

Trim long urls

You have the possiblity to set the maximum lenght a url can have;

label.urlMaximumLength = 30

From now on, a url that's bigger than that, will be trimmed.


mentionColor: UIColor = .blueColor()
mentionSelectedColor: UIColor?
hashtagColor: UIColor = .blueColor()
hashtagSelectedColor: UIColor?
URLColor: UIColor = .blueColor()
URLSelectedColor: UIColor?
customColor: [ActiveType : UIColor]
customSelectedColor: [ActiveType : UIColor]
lineSpacing: Float?
handleMentionTap: (String) -> ()
label.handleMentionTap { userHandle in print("\(userHandle) tapped") }
handleHashtagTap: (String) -> ()
label.handleHashtagTap { hashtag in print("\(hashtag) tapped") }
handleURLTap: (NSURL) -> ()
label.handleURLTap { url in UIApplication.shared.openURL(url) }
handleCustomTap(for type: ActiveType, handler: (String) -> ())
label.handleCustomTap(for: customType) { element in print("\(element) tapped") }
filterHashtag: (String) -> Bool
label.filterHashtag { hashtag in validHashtags.contains(hashtag) }
filterMention: (String) -> Bool
label.filterMention { mention in validMentions.contains(mention) }


Before writing

we've tried a lot of the following alternatives but weren't quite satisfied with the quality level or ease of usage, so we decided to contribute our own solution.
  • TTTAttributedLabel (ObjC) - A drop-in replacement for UILabel that supports attributes, data detectors, links, and more
  • STTweetLabel (ObjC) - A UILabel with #hashtag @handle and links tappable
  • AMAttributedHighlightLabel (ObjC) - A UILabel subclass with mention/hashtag/link highlighting
  • KILabel (ObjC) - A simple to use drop in replacement for UILabel for iOS 7 and above that highlights links such as URLs, twitter style usernames and hashtags and makes them touchable
